Due to the merits of OLED displays such as fast responsiveness, wide view angle, and power efficiency, their use has increased. However, despite the power efficiency of OLED displays, the portion of their power consumption among the total power consumption is still high since user interaction-based applications such as instant messaging, video play, and games are frequently used. Their power consumption varies significantly depending on the display contents and thus color transformation is one of the low-power techniques used in OLED displays. Prior low-power color transformation techniques have not been rigorously studied in terms of satisfaction of the human visual system, and have not considered optimal visual satisfaction and power consumption at the same time in relation to color transformation. In this paper, we propose a novel low-power color transformation technique which strictly considers human visual system-awareness as well as optimization of both visual satisfaction and power consumption in a balanced way. Experimental results show that the proposed technique achieves better human visual satisfaction in terms of visuality and also shows on average 13.4% and 22.4% improvement over a prior one in terms of power saving.

The purpose of this study was to investigate how brand identity expressional elements in cosmetic road shops' facades would affect the brand awareness of consumers while extracting those brand identity expressional elements observed in the facades of the cosmetic road shops. In order to achieve the research goal, the study used Q methodology, a method to measure subjectivity. The results have been summarized as follows. (1) The elements to express the brand identity found in the facades of the cosmetic road shops were observed to be two-dimensional expressional elements, and they should include a symbol, a logo, a signboard, materials to express an image (products, models) and a brand color. As for the three-dimensional expressional elements, they were a building (form, materials, pattern), decorations (lean-to roof, canopy, sculptures, lighting, screen) and a display window (focusing on products, visuality or the inside of a shop). (2) The findings of the analyses on the brand awareness using Q methodology have been presented as follows. (1) When multiple identity expressional elements which would be associated with each other are used, the brand awareness gets increased relatively efficiently. (2) In case of men, they would perceive a brand more easily through those formative expressional elements such as a form of a building. (3) In case of women, they would perceive a brand more conveniently through those visual expressional elements such as a brand color. (3) In conclusion, the study figured out that, among the brand identity expressional elements, the one which would influence the brand awareness most would be (1) the brand color, followed by (2) the building-form, (3) the lean-to roof, (4) the display window and (5) the logo. Based upon what has been learned so far, the study confirmed that when it comes to securing the brand awareness in the market, cosmetic companies should, first, realize how important it is to make good use of the two-dimensional (visual) expressional element, the brand color, and the three-dimensional expressional element, the form of the building, together before they even try to design facades of their shops on the streets.

The purpose of this study is to find methods for building the community in poor residential environments. We analyze the public art project, "The Rose of Sharon Blooms," in Daejeon. To understand the project we interviewed artists, curators, local residents, and visitors, about three aspects of public art: visuality, speciality, and communication with citizens. These stakeholder interviews yielded valuable knowledge and insights: First, artworks created from the residents' recycled junk effectively harmonizes and unifies the citizens and their environment. Second, managing a gallery in the neighborhood symbolically values and explicates the public art project and thus enhanced the local identity. Third, public workshops in the neighborhood provide a venue for local citizens to communicate with visitors about the public arts, which eventually led to the welcoming atmosphere of the community. However, we found relatively little awareness of the need for partnership aspects among our interviewees, which suggests the importance of ongoing cooperation with other arts institutions and researchers to build vital cultural linkages and introduce varied art forms.

This study analyzed the influence of the perception of physical environment on user satisfaction and park use when people use the park to improve their health. The study is focused on neighborhood parks in Suseong-gu, Daegu city. Statistical analyses were employed to data collected from 143 visitors on site. First of all, in the perception evaluation of the physical environment of the park, accessibility and pedestrian environment are the highest at 4.04, while water space and attractions in the park as the lowest parts are at 2.32 and 2.66. After conduct factor analysis to type 22 physical environmental awareness components, five main factors--Comfort, Availability, Amenity, Facilities convenience and Visuality--were classified. Then, satisfaction and influence on park use were analyzed. As a result, the factors affecting user satisfaction were comfort, availability, amenity and facility convenience. Among them, the category of amenity was the most influential factor at 0.315. The factors affecting the park use were availability and amenity. Availability factor had a higher influence at 0.396 than amenity at 0.293. Therefore, in order to improve satisfaction and park use for health improvement, it is necessary to secure sufficient green areas and create a pleasant environment. Also, it is necessary to improve the quality of walkability from homes to parks, trail improvement and other improvements.
